Life is short, I use Python!

NameError: name 'pygame' is not defined

TypeError: size must be two numbers

TypeError: function takes at least 1 argument (0 given)

1. Installation of Pygame library

First, we press the Win+R keys, enter cmd, and press Enter.

Then, enter"python -m pip install -U pygame --user",and press Enter to install .

When the progress bar finally reaches 100%, the installation is completed.

2. Formal explanation

2.1 Start function

The method is very simple, it is the init() function.

Example:

import pygame  #导入pygame
pygame.init()

2.2 Create window

After pygame.init(), a window must be created. This is the pyame.display.set_mode() method.

The syntax is:

pygame.display.set_mode([width，height])

Note: It is often necessary to save it in a variable for easy calling.

Example:

import pygame  #导入pygame

pygame.init()
screen=pygame.display.set_mode([1500,1000])  #创建一个宽1500像素，高1000像素的Surface对象，命名为screen

2.3 Modify name

If you need to change the window name, you need the pygame.display.set_caption() method.

Its parameter is of str type (A string enclosed in double quotes).

Example:

import pygame  #导入pygame

pygame.init()
screen=pygame.display.set_mode([1500,1000])  #创建一个宽1500像素，高1000像素的Surface对象，命名为screen

pygame.display.set_caption("我的pyame窗口")   #命名窗口为“我的pygame”窗口

3. Eliminate errors

NameError: name 'pygame' is not defined

This error is very simple. The reason is that you forgot to import the pygame library. Just add import pygame in the first line.

TypeError: size must be two numbers

This error, translated, is:The size must be two numbers.

You need to find the pygame.display.set_mode() function,Enlarge the two numbers with "()" or "[ ]".

TypeError: function takes at least 1 argument (0 given)

This error, the translation is:This function takes at least 1 parameter (0 parameters are passed).

Just complete the parameters.
